SIEPARABLE CUFF-BUTTON.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed February 7, 1920. Serial No. 857,025.

To all whom it may concern: I

Be it known that I, J OSEPI-I J. BERNIER, a citizen of the United States, residing at Chartley, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Separable Cuff-Buttons, of which the following is a specification.

My invention relates to cuff buttons or fasteners of the pull apart type, and has for its essential objects inexpensiveness of construction; security against accidental separation of constituent parts; and strength.

To the above ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification'- Figures land 2 are plan elevations of the blanks from which are formed the entering and receiving members respectively of my cuff button or fastener,

Fig. 3, a longitudinal central section of both members of the device in engaged position,

Fig. 4:, a detail plan of the entering member,

Fig. 5, a her, and

Fig. 6, a side elevation, partially in central longitudinal section, of a modified form of my device.

Like reference characters indicate like parts throughout the views.

My novel structure comprises two separable interengaging elements herein referred to as the entering member and the receiving member.

In forming the entering member a blank, such as that shown in Fig. 1, is by suitable tools cut from a sheet metal strip, comprising a disk 9 having peripheral arms 10 in alinement with each other, upon whose outer ends are semicircular sections or segments 11 having their plane edges at the extremities of the blank. Centrally of the edges project fingers or necks 12 terminating in circular portions 13 bent up by suitable tools into cups or hemispherical hollow heads either simultaneously with the cutting operation or subsequently.

The described blank is next bent into the form shown in Fig. 4 comprising a base or head 9 from which rise inwardly curved,

like plan of the receiving memoppositely disposed, arms 10 integral with the curved portions of the inturned sections 11. The two sections 11 lie in a common plane parallel with the portion 9 and constitute an abutment. The plane edges of the sections 11 are in this instance slightly spaced from each other. The fingers 12 and heads 13 are parallel with each other at right angles to the abutment.

The receiving member is formed from the blank shown in Fig. 2, cut from a strip ofthin metal, comprising a central disk 15 provided with a central circular opening 16, and having oppositely disposed arms 17 merging into the peripheral portions of semicircular sections 18 of greater width than the diameter of the portion 15. This blank is bent up as shown in Fig. 5 with the disk forming an abutment supported by peripheral inwardly curved arms 17 rising from the curved edges of the inwardly directed sections 18 whose plane edges abut each other as at 19 and together constitut the head or base of the member.

v The diameter of the opening 16 is suflicient to permit passage therethrouglii of the members 13, when the latter are compressed, by virtue of the resilient fingers 12. After such passage the fingers expand to normal position making the diameter of the members 13 0 positioned greater than the diame ter of the opening 16. This form of interengagement allows relative oscillatory or two direction movement of both button members.

The margins of the cuff button holes are afforded retaining seats by the concaved arms 10 and 17 intermediate the larger members 9 and 11, and 18 and 15 respectively.

It will be observed that the members 13 are nowhere in contact with any portion of the receiving member except the abutment 15. This fact insures a maximum expansion of the fingers 12 after interengagement of the button parts and thus diminishes the chance of accidental disengagement of the engaged parts.

It will be further noted that the described structure adapts itself to a single piece construction of each button member and a resultant saving in labor and expense of construction.

In the construction shown in Figs. 3 to 5 inclusive a complete button is shown, the members 9 and 18 forming the ornamental heads. Further opportunity for ornamentation is aflorded, if desired, by applying in any convenient manner face plates. Such a cor-struction is shown in Fi 6 wherein a plate 21 on the tace-of headt) has an annular flange 22 surrounding the latter, with its edge 23 beaded over the same. A like plate 25 on the head 18, with a flange 26'has a bead 27.

I claim 1- 1. In a cuff fastener, an entering member comprising ahead, ,an abutment, arms uniting the head and abutment, spaced com- ,pressible fingers on theabutmenuand heads abutment, compressible resilient fingers on the abutment, curved heads on -the,-fingers,

and a receiving member comprising, a head,

an abutment, and concave marginal arms uniting the second head and the second abutment,-the second abutment being prov ded -=with an opening adapted to admit the curved heads therethrough when the fingers are compressed.

3. In tahcu ff fastener an entering member comprising in a single piece of sheet -metal ahead, marginal arms upon the head,

when the fingers are compressed.

4. In a cuff fastener, a receiving member comprising in a-singlepiece of sheet metal an abutment provided with a central open ing, concave marginal'arms on the abutment, .inturned semi-circular head sections on the arms provided with abutting plane edges, and an entering member comprising a head, and abutment, arms connecting the last head and the lastabutment, compressible fingers onthelast abutment, and heads on the fingers movable through the opening only when the fingers are compressed.

In testimony whereof I have affixed my signature.

J OSEPHIJ BERNIER.
